First you need to initialize the Gnuplot environment // Load a support library GaussGnuplot.dll from MTENGHOME?? dlib dlibrary GaussGnuplot; // Set local variables local np,xpp,ypp,cp,titl,text; // Initialize an Gnuplot environment dllcall -r GnuplotInit;Next, you need to create a plot window, for example // Create an output window np=1; xpp=40; ypp=40; cp=1; dllcall GnuplotWindowRelative(np,xpp,ypp,cp); // 1 %u2013 plot number, 40% of screen size, centeredThen, an arbitrary set of plot creation statements can be used depending on the plot to be produced titl=\dllcall GnuplotWindowTitle(np,titl); text=\dllcall GnuplotPut(np,text);...Finally, all collected plot elements can be shown by dllcall GnuplotShow(np);and Gnuplot environment need to be closed by dllcall GnuplotEnd;
